While this works great, with co-routines we can simplify things by removing the conditional logic. In a coroutine when you 'await' you are suspending the function, so it resumes where it left off.

async def update():
    n = 255
    while True:
        for x in range(n+1):
            await asyncio.sleep(0.1)
            self.color = Color(x,0,0)
        for x in range(n-1,0,-1):
            await asyncio.sleep(0.1)
            self.color = Color(x,0,0)

Better yet we could also do something like if you wanted to reuse the functionality.

async def update():
    async for x in thereAndBackIncrementor(0,10):
        self.color = Color(x,0,0)
        await asyncio.sleep(0.1)


async def thereAndBackIncrementor(firstVal,lastVal):
    for x in range(lastVal + 1):
        yield x
    for x in range(lastVal - 1, firstVal, -1):
        yield x
